That's correct, Insure & Go is the underwriter for both Insure & Go's products as well as Virgin Travel Insurance. Virgin Money does its own branding, pricing (similar products by the two companies have different prices - Virgin's seems higher), and customer support / claims (Virgin handles that for its own products). If you don't want to read a dense policy wording document, have a look at the 'keyfacts' document all insurance providers in the UK are supposed to publish to compare for Virgin Money and Insure & Go.
